Thanks for the tip. It looks like for remote files, mozplugger is
creating the tmpfile in <instancedir>/tmp, and somehow, the ds is not
creating a copy of that file (I get a journal entry, but there's no
file which is loaded subsequently by Read)
Disabling security, or saving a local file seems to work fine though.
I'm using the same code as in copy-to-journal
